Iframe HTML code not working on Android/iOS

As the title says, for web the following initial content works:
```
<iframe src="//gadgets.buienradar.nl/
gadget/forecastandstation/6275/" noresize scrolling=no hspace=0
vspace=0 frameborder=0 marginheight=0 marginwidth=0 width=300 height=190></ iframe>
```

on android and ios it results in a whitescreen.
